 * Vector that uses realloc() instead of new/malloc(). Significantly faster than std::vector, but has problems with objects that are not `std::trivially_relocatable`.
 * Copy-on-write used in several places; paged arrays to used copy-on-write in arrays
 * Reference-counted strings to avoid copying strings. Bunch of `constexpr` stuff used to make static initialization (i.e. program startup) faster.

STL

Wrap an existing C-style pointer to an array with std::vector: http://stackoverflow.com/a/15203325/14878; modifies std::vector internals to work.

C++11

Move semantics/perfect forwarding

Smart pointers

Data structures

B-tree-based maps & sets

  • In 2013, Google open-sourced a mostly-STL-compatible b-tree implementation: B-tree containers from Google. The old project is on Google code, but JGRennison/cpp-btree is a fork with minor fixes and some C++11 support (e.g. move constructors, etc).

  • bingmann/stx-btree

  • tlx library contains a fast loser tree implementation, a newer version of the bingmann/stx-btree implemtnation, a smart pointer replacement for shared_ptr called counting_ptr, and std::string helper functions missing from STL.
